Any app tracking devices used in the past to locate Razorback Transit buses are no longer valid.

According to Razorback Transit Operations Supervisor Ed McCawley no other apps will matter except the Passio GO! app.

One app that people used in the past to track Razorback Transit routes wasn't even affiliated with Transit and Parking.

But the Passio GO! app is.

"It is the only official Razorback Transit bus app," McCawley said.

Passio Technologies is a nationwide company that provides tracking of public transit, and Razorback Transit is now in their system.

Passengers are encouraged to download the app and use it.

Razorback Transit will continue to have a full slate of bus routes though Thursday, May 9. After that, reduced service will be provided during the summer months. A full schedule through the summer is available by downloading the Transit 2018-19 Calendar PDF.
